Suppose that you were called upon to give some advice to a lawyer concerning the physics involved in one of his cases. The question is whether a driver was exceeding a 30 mph speed limit before he made an emergency stop, brakes locked and wheels sliding. The length of the skid marks on the road was 19.2 ft. The policeman made the reasonable assumption that the maximum deceleration of the car would not exceed the acceleration of a freely falling body and arrested the driver for speeding. Determine whether or not his decision is correct.

Suppose that you were called upon to give some advice to a lawyer concerning the
physics involved in one of his cases. The question is whether a driver was exceeding a
30 mph speed limit before he made an emergency stop, brakes locked and wheels sliding.
The length of the skid marks on the road was 19.2 ft. The policeman made the
reasonable assumption that the maximum deceleration of the car would not exceed the
acceleration of a freely falling body and arrested the driver for speeding. Determine
whether or not his decision is correct.
